Title:
RESPONSE ELEMENT AND PREPARATION THEREOF
Document Type and Number:
Japanese Patent JPH01119713
Kind Code:
A
Abstract:
PURPOSE:To obtain the title element having high mechanical strength, usable in an arbitrary shape and large in change quantity, by combining a precursor of a swellable and shrinkable polymer gel with a microporous body to perform reaction. CONSTITUTION:A precursor of a swellable and shrinkable polymer gel functioning reversibly by the change of environment such as temp. or a solvent composition and a microporous body having micropores are combined and reacted to bear the role of both of or either one of reinforcing effect and shape imparting. In said combination, both of them are brought to surface contact or either one of them is wrapped in the other. The reaction is performed in order to change the precursor of the swellable and shrinkable polymer gel to a swellable and shrinkable polymer gel and there is polymerization, crosslinking or a combination of both of them. By this method, the title responsive element having high mechanical strength, usable in an arbitrary shape such as a sheet like shape, a fibrous shape, a hollow fiber like shape or a combination thereof, keeping change quantity at the time of the polymer gel alone and applicable to a wide field is obtained.
